CGPA to Percentage Calculator

Convert CGPA to percentage free online — no signup, no data stored. This CGPA to percentage calculator works the careful way: by university. Enter your CGPA, choose your university, and the tool applies that university's official rule with the formula written out in your numbers and a link to the official university document it comes from. There is no single national formula hiding behind this page, and pretending otherwise would give many students a wrong percentage.

Why the university selector decides everything

Two students with the same 8.00 CGPA can legitimately receive different percentages, because each university publishes its own official conversion. Under VTU's 2022 scheme rule, Percentage = CGPA × 10, so 8.00 becomes 80.00%; under VTU's 2015–2018 scheme rule, (CGPA − 0.75) × 10, the same 8.00 becomes 72.50%; and under JNTUH's official rule, (CGPA − 0.5) × 10, it becomes 75.00%. Every result names the rule, the scheme it applies to, and links the official source — VTU's CGPA Standard Formula page ↗, VTU Regulations 2022 (PDF) ↗, JNTUH Academic Regulations R18 (PDF) ↗ — so you can open the same document and check the rule for your own batch. Mumbai University is the exception by its own decision: it repealed formula conversion on 1 January 2026, so its percentage now comes from actual marks, as its official 2026 circular ↗ explains.

How to convert CGPA to percentage

First calculate an accurate CGPA — the SGPA to CGPA calculator does this from semester SGPAs with or without credits. Then enter that CGPA here without rounding it down first; rounding 8.46 to 8.4 before converting quietly shaves marks off the percentage. With every result you get the exact rule used, the scheme it applies to, and a link to the official university document — open it and match the rule to your own regulation year, because universities revise notifications and a senior’s circular may not govern your batch.

CGPA to percentage formula

There is no one CGPA to percentage formula for every student in India. Each university notifies its own conversion, which is why this page always starts from the university you select. Where a linear rule is loaded, the CGPA to percentage calculation is: Percentage = (CGPA − offset) × multiplier, using that university's offset and multiplier. The calculator shows the rule, the scheme it applies to, and a link to the official university source with every result.

CGPA to percentage conversion table

The table below uses official rules published by the universities: VTU 2022 scheme (CGPA × 10), VTU 2015–2018 schemes ((CGPA − 0.75) × 10) and JNTUH ((CGPA − 0.5) × 10). Pick the column for your university and scheme — the calculator above does this automatically and links the official document for each rule.

Every university in the calculator — VTU, JNTUH, KTU, SPPU, JNTUK, SRM, Mumbai, Calcutta and Calicut — now converts with its own official rule or official process, linked from the result. Use the Percentage to CGPA calculator for the reverse conversion. SPPU students: see the dedicated CGPA to Percentage SPPU guide.

Common percentage mistakes

• Assuming one fixed multiplier fits every university. It does not; the selector exists for this reason.
• Quoting a converted percentage without its source — keep the university rule and scheme next to the figure, exactly as the result card shows them.
• Rounding the CGPA early, then converting the rounded value.
• Using a percentage-to-CGPA table backwards without checking whether the university’s rule is actually linear and invertible; our Percentage to CGPA calculator only inverts a rule that is loaded for the selected university.

Universities and boards covered

This calculator covers 172 universities, institutes and boards across India — each one converting with its own official published rule, from VTU, Anna University and the NITs to state universities and CBSE. To keep this page focused on converting, the full list lives on its own page, grouped by state:
